This research assessed mud crab culture practices and market distribution in Santa Teresita, Cagayan, Philippines- one of the crab culture municipalities in the province. A total of 80 mud crab key stakeholders (grow-out farmers, fatteners, dealers, retailers, and peddlers) were interviewed to gather data. The results showed that most of the mud crab farmers were male (70 %), while traders were dominantly female (97.5 %). Among the 40 mud crab farmers, 82.5 % were involved in grow-out (poly and monoculture), while 17.5 % were involved in fattening. The respondents revealed that the constraints hindering the sustainability of mud crab culture in the area included: intra-species cannibalism, flooding, limited knowledge in crab farming, and inconsistent supply of quality crab seeds. There were 6 different marketing chains identified in the area, involving different stakeholders, with Crab Farmer-Retailer-Consumer being the most common distribution pattern. The results of this research are good input for the development of a municipal mud crab management plan.
